B.4  Signalling Scenarios (informative)  p. 49

This (informative) clause contains examples of signalling scenarios.

B.4.1  Delivery of SMS to a Non-ported Number - Direct Routeing - MNP-SRF acts as SCCP Relay  p. 49

Figure B.4.1 shows the MNP-SRF operation for delivering an SMS message to a non-ported number.

  1. The SMSC forwards a SM to the SMS-GMSC via a proprietary interface.
  2. The SMS-GMSC generates a routeing enquiry for SM delivery. The MAP SRI_for_SM message is routed to the network's MNP-SRF.
  3. When MNP-SRFB receives the message, MNP-SRF operation is triggered. The MNP-SRF functionality analyses the MSISDN in the CdPA and identifies the MSISDN as being non-ported using information which may be retrieved from an NP database. The MNP-SRF function then populates the CdPA with an HLRB address. After modifying the CdPA, the message is routed to HLRB.
  4. HLRB responds to the routeing enquiry by sending back an SRI_for_SM ack with the address of the VMSC.
  5. The SMS-GMSC can now deliver the message to the VMSCB using a Forward_SMS message.
  6. VMSCB further delivers the message to MSB.

B.4.2  Delivery of SMS to a Non-ported Number - Direct Routeing - MNP-SRF acts as Higher-level Relay  p. 50

Figure B.4.2 shows the MNP-SRF operation for delivering an SMS message to a non-ported number where the SRI_for_SM message is submitted by a national interrogating network. For further details of the higher level relay function (e.g. TC relay), the reader is referred to [7].

  1. The SMSC forwards a SM to the SMS-GMSC via a proprietary interface.
  2. The SMS-GMSC generates a routeing enquiry for SM delivery. The MAP SRI_for_SM message is routed to the network's MNP-SRF.
  3. When MNP-SRFB receives the message it terminates the TCAP dialogue and an MNP-SRF operation is triggered. The MNP-SRF functionality analyses the MSISDN in the TCAP portion of the message and identifies the MSISDN as being non-ported using information which may be retrieved from an NP database. The MNP-SRF function then initiates a new dialogue and routes the message to HLRB.
  4. HLRB responds to the routeing enquiry by sending back an SRI_for_SM ack with the address of the VMSC.
  5. MNP-SRFB responds to the routeing enquiry by sending back an SRI_for_SM ack with the address of the VMSC to the SMS-GMSCA.
  6. The SMS-GMSC can now deliver the message to the VMSCB using a Forward_SMS message.
  7. VMSCB further delivers the message to MSB.

B.4.3  Delivery of SMS to a Ported Number - Indirect Routeing  p. 51

Figure B.4.3 shows the MNP-SRF operation for delivering an SMS message to a ported number where the interrogating network does not support direct routeing.
The message flows for this scenario are based on the use of an SCCP-relay function in the MNP-SRF(s). If the MNP-SRF(s) use(s) a higher-level relay function (e.g. TC-relay), then the response message will go via the MNP-SRF as shown in clause B.4.2. For further details of the signalling relay functions, the reader is referred to [7].

  1. The SMSC forwards a SM to the SMS-GMSC via a proprietary interface.
  2. The SMS-GMSC generates a routeing enquiry for SM delivery. The MAP SRI_for_SM message is routed to the number range holder network's MNP-SRF.
  3. When MNP-SRFB' receives the message, MNP-SRF operation is triggered. The MNP-SRF functionality analyses the MSISDN in the CdPA and identifies the MSISDN as being ported using information which may be retrieved from an NP database. As the message is non-call related, the MNP-SRF function then populates the CdPA with either a routeing number or a concatenation of a routeing number and MSISDN. After modifying the CdPA, the message is routed to MNP-SRFB in the subscription network.
  4. When MNP-SRFB receives the message, MNP-SRF operation is triggered. The MNP-SRF functionality analyses the MSISDN in the CdPA and identifies the MSISDN as being ported into the network using information which may be retrieved from an NP database. The MNP-SRF function then populates the CdPA with an HLRB address. After modifying the CdPA, the message is routed to HLRB.
  5. HLRB responds to the routeing enquiry by sending back an SRI_for_SM ack with the address of the VMSC.
  6. The SMS-GMSC can now deliver the message to the VMSCB using a Forward_SMS message.
  7. VMSCB further delivers the message to MSB.
